Analysis on the factors associated with treatment failure of using anesthetics in refractory status epilepticus
Abstract
Objective To analyze the related factors associated with immediate treatment failure of using anesthetics in refractory status epilepticus (RSE). Methods Thirty patients derived from Neurocritical Care Unit of Xuanwu Hospital from January 2004 to December 2013 were divided into 2 groups (acute treatment failure group and acute treatment success group) based on the treatment outcome 6 h after intravenous injection of anesthetics. Univariate and multivariate forward Logistic regression analyses were used to analyze and screen the risk factors associated with immediate treatment failure, and calculate the failure rate of final outcome. Results According to the results of univariate and multivariate Logistic regression analyses, among influencing factors such as sex, age, etiology, Acute Physiology and Chronic Health EvaluationⅡ (APACHEⅡ), type of status epilepticus (SE), type of antiepileptic drugs (AEDs), total duration of primary treatment, duration of prehospital primary treatment, duration of posthospital primary treatment, type of RSE and primary choice of anesthetics, only total duration of primary treatment was the independent risk factor for immediate treatment failure (OR = 1.007, 95%CI: 1.000-1.014; P = 0.047). The rate of immediate treatment failure of RSE by using anesthetics was 50% (15/30), and the rate of final treatment failure was 43.33% (13/30). The ratio of final treatment failure was much higher in acute treatment failure group than that in acute treatment success group (10/15 vs 3/15, P = 0.025). Conclusions The acute treatment result of RSE depends on the total duration of primary treatment, and determinates the final result of treatment. On the basis of treating primary disease, the therapy to terminate SE or RSE should be started as early as possible. DOI: 10.3969/j.issn.1672-6731.2015.11.008
